FABRIC CARE SYMBOLS:
Always check the bolt end or label for washing instructions
Pre-wash fabric before cutting (shrinkage prevention)
Pre-wash the same way you'll wash the finished garment
Fabric Selection Tips
BEGINNER-FRIENDLY FABRICS:
1. Quilting cotton (doesn't stretch, easy to handle)
2. Flannel (slightly fuzzy, stays in place)
3. Chambray (light denim feel, well-behaved)
4. Medium-weight linen (forgiving, beautiful drape)
AVOID AS A BEGINNER:
- Silk and satin (slippery, every mistake shows)
- Chiffon and sheers (hard to handle, seams visible)
- Stretchy knits without a walking foot or serger
- Very thick materials like upholstery fabric
- Velvet (shifts, shows marks)
FABRIC MATH:
Most fabric comes in 44-45" or 54-60" widths
Pattern envelope lists yardage needed for each size
Add 10-15% extra for matching prints, mistakes, or shrinkage
"With nap" yardage = all pieces cut in same direction (velvet, corduroy)
Pattern Reading
Understanding a Sewing Pattern
PATTERN ENVELOPE:
Front: Photo/illustration of finished garment
Back:
- Line drawings of all included views/variations
- Size chart (compare YOUR measurements to pattern, not RTW sizes)
- Fabric suggestions
- Yardage requirements by size and view
- Notions needed (zipper, buttons, elastic, etc.)
PATTERN PIECES:
Grain line arrow: Must align with fabric selvage (parallel)
"Place on fold": Pattern edge goes on fabric fold (creates symmetric piece)
Notches: Alignment marks (match single to single, double to double)
Dots/circles: Match points for construction
Darts: Triangular markings for shaping (bust, waist, back)
Cutting line: Outer solid line (cut here)
Stitching line: Inner dashed line (sew here)
Seam allowance: Space between cutting and stitching line
Commercial patterns: Usually 5/8" (15mm)
Indie patterns: Often 3/8" or 1/2" (check instructions)
TAKING MEASUREMENTS:
Bust: Around fullest part of chest, over bra
Waist: Natural waist, narrowest point (bend to the side, crease is your waist)
Hips: Around fullest part of hips/seat (usually 7-9" below waist)
Back waist length: Nape of neck to natural waist
Compare to pattern size chart, NOT to ready-to-wear sizes
Choose size based on largest measurement, then adjust others
Pattern Adjustments
COMMON ADJUSTMENTS:
Full bust adjustment (FBA): Add width at bust for larger cup sizes
Small bust adjustment (SBA): Remove width for smaller cup sizes
Lengthen/shorten: Cut and spread or overlap at adjustment lines
Wide/narrow shoulders: Adjust at shoulder seam
Grading between sizes: Use one size at bust, blend to another at hips
EASE:
Wearing ease: Extra room for comfortable movement (built into patterns)
Design ease: Extra room for the style (oversized, fitted, etc.)
Negative ease: Pattern is smaller than body (stretchy fabrics only)
Basic Stitches
Machine Stitches
STRAIGHT STITCH:
Most-used stitch for woven fabrics
Length: 2.5mm (standard), 3.0-4.0mm (basting/gathering)
Backstitch at start and end to secure
ZIGZAG STITCH:
Use: Stretch seams, raw edge finishing, applique
Width: Narrow for seam finishing, wide for applique
Length: 1.0-2.0mm depending on application
BASTING STITCH:
Longest straight stitch (4.0-5.0mm)
No backstitching (temporary, meant to be removed)
Use: Testing fit, gathering, holding pieces for permanent sewing
BUTTONHOLE:
Most machines have a buttonhole foot and automatic function
Always test on scrap fabric first
Use interfacing behind buttonhole area for stability
OVERLOCK/OVERCASTING STITCH:
Built-in stitch that mimics serger
Use: Finishing raw edges on woven fabrics
Not a substitute for a true serger on knits
Hand Stitches
SLIP STITCH (LADDER STITCH):
Use: Invisible closing of openings, hems, linings
Technique: Alternate tiny stitches between folded edges
BACKSTITCH:
Use: Strong seam by hand, repairs
Technique: Forward one stitch, back into previous stitch hole
WHIP STITCH:
Use: Closing openings, attaching patches, quick repairs
Technique: Diagonal stitches over the edge
BLIND HEM STITCH:
Use: Invisible hems on dress pants, skirts
Technique: Catch 1-2 threads of outer fabric, larger stitch in hem fold
BASTING:
Use: Temporary hold for fitting, ease adjustment
Technique: Long running stitches, easy to remove
BLANKET STITCH:
Use: Decorative edges, felt crafts, applique
Technique: Loop stitch along the edge
Garment Construction
Construction Order (Standard Garment)
GENERAL SEQUENCE:
1. Prepare pattern pieces and cut fabric
2. Transfer all markings to fabric
3. Sew darts (if any)
4. Sew all structural seams (shoulder seams, side seams)
5. Insert sleeves (set-in) or attach bodice to skirt
6. Sew secondary seams (inseam for pants, sleeve seams)
7. Apply facings or neckline finish
8. Install closures (zipper, buttons)
9. Hem garment
10. Final pressing
PRESSING RULES:
Press every seam BEFORE crossing it with another seam
Press seams open for flat construction
Press seams to one side for strength (toward darker fabric)
Press darts toward center front/back (bust darts downward)
Use a pressing cloth on delicate or synthetic fabrics
Seam Finishing Methods

Common Mistakes to Avoid
- Not pre-washing fabric (shrinkage after construction ruins the garment)
- Cutting with dull scissors or not following grain line
- Skipping pressing between steps (pressing is 50% of professional results)
- Using the wrong needle for the fabric type
- Not backstitching at seam starts and ends (seams come apart)
- Pulling or pushing fabric through the machine (let the feed dogs do it)
- Ignoring seam allowances or assuming they're always 5/8"
- Not testing stitch length and tension on scrap fabric first
- skipping to change your machine needle regularly (every 8-12 hours of sewing)
- Trying to cut corners on fitting (fit as you go, not at the end)
